Brake discs Zimmermann or Raybestos

I used Zimmermann replacements discs and pads on my B9 RS4 for 5 years/70k miles. Had 3 sets all around over that time. The front discs and calipers are the same as the etron. They were good products and hard to tell the difference from OEM.

I replaced the front pads and rotors on my F20 M135i yesterday. Same Brembo brakes as yours. I did a lot of research, and there isn't really "better" than stock for the same money. The only better option would be to upgrade to bigger brakes, but that would cost way more. I ended up going with Zimmerman Z-coat two piece rotors and ATE pads. The Zimmerman rotors are the slotted and dimpled versions. BMW calls that the M Performance rotors as OE. They're the same size - 340mm. They reportedly don't give much of a performance increase, but they weigh about 8% less than standard discs. All together with the hardware (guide pins, caliper bolts, etc) was about £500 with shipping from Spareto.

ngl i just installed zimmerman rotors and they probably had that too but no problems

Anyways based off your post history looks like you’re in Sauga, so you can probably go to Parts Avatar. Place an online order and drive over there to pick it up at their warehouse.

The Budget Plan:

Rotors - Raybestos Element 3 980952FZN

I ordered zimmerman rotors and genaric TWR ceramic pads

I just did pads and rotors on my '19 Alltrack. I went with Bosch Quietcast pads and Zimmermann rotors from FCP Euro. So much better than the OEM I removed.

Do not go cheap. I even tried the top-of-the-line products house brand from AutoZone and advance auto parts. The front rotors warp in three to 6 months even their premium products. I struggled with this for years trying to figure out what it was. I switched to Raybestos element 3 problem solved. Do not go cheap on the front.

I keep hearing my brakes squeal when I drive and it's really bothering, so I'm trying to figure out what could be causing it or if it's something I have to deal with. I bought a Zimmermann kit with Textar semi metallic pads. My buddy thinks I should've removed the Coat Z anticorrosive off the rotors before installing but it says on their website it's made to be installed with it on. The only thing I can think of is maybe I didn't lube the moving surfaces enough or I need to do a better job bedding them in.
